To all whom it may concern:

Be it known that I, Jorrn W. Nrrrnn'r, a citizen of the United States, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented. cer tain new and useful Improvements in SpringW'heels, of which the following is a specification, reference being bad to the ac companying drawings.

The present invention relates to new and useful improvements in spring wheels designed to be used in conjunction with motor vehicles or the like and the primary object of the present invention is to provide a cushioning device for wheels of this character which is composed of a plurality of sections wherebythe same may be easily and readily removed and new sections substituted in their place should the same becomeworn or broken thereby increasing the life of the wheel;

Another object of the present invention is to provide a device of this character which will be comparatively inexpensive in the cost to manufacture, strong, durable, and eiiicient when in use, and having the parts thereof adapted to be readily assembled and installed thereby rendering the device com-. mercially desirable.

With the above and other objects in view the invention consists of the novel details arrangement of partsas will'be hereinafter more fully described and particularlypointed out in the accompanying drawings in which- 7 Figure 1 is a side elevation of the wheel having portions of the outer plate removed therefrom, Fig. 2 is a I vertical section through the same, Fig. 3 is a detail sectional' view on the line 3-,?) of Fig. 1, Fig. 4 is a horizontal sectional view through one of the jacks, and Fig. 5 is a detail perspective view. 7 l

Reference now beinghad to the accompanying drawings wherein like and corresponding arts are designated by similar reference c aracters' throughoutthe several views the wheel comprises an ordinary hub 1 having secured thereto a plurality of radially extending spokes 2 bein secured at their outer end to a rim 3. n outer rim 4 is spaced from the rim 3 by means'ofmy improved cushioning device and is adapted to be secured thereto as willbe hereinafter more fully described.

The cushioning device proper forming the sub ect matter-ofthe present invention com prises a band 5 which is adapted to rest upon the outer periphery of the inner-rim 3 havmg secured thereto a plurality of sections forming the cushioning device between the inner and outer rims ,3 and lrespectively which also holds the rims in proper position.

The sections of the cushioning device comprise outer and inner rim sections 6 and 7 respectively which are preferably made of segmental pieces of flat metal. Formed upon the inner face of each of the rim sections 6 and 7 respectively are a plurality of alining recessed projections 8 in each of which is adapted to rest a coil spring 9. lit is apparent from the foregoingthat in assembling the wheel the inner shoe' 7 is secured to the outer periphery of the band 5 by means of rivets 10 or the like andthecoil springs are placed between the two .rim sec tions and thence the outer rim section 6 rests upon. the inner periphery of the outer rim 4;,

Owing to the expansion of the "coil springs 9 it is found to be a difficult matter to insert the cushioning devices between the inner and outer rims 3 and a respectively and so l have provided within each section a pair of detachably mounted jacks 11 which will act against the expansion of the coil spring and permit the sections of the cushioning device to be readily inserted in place, Formed integral upon the opposing faces of the rim sections 6 and 7, respectively, are alining recessed bosses 12. and 13, respectively, which are positioned between the. recessed projections 8, as shown. An adjust able screw 14: is adaptedto be mounted within .each of the bosses 12 and 13 so that when the coil springs 9 are placed between said rim sections, the screw 14 may be adjusted until the distance between the two rim sections 6 and 7 is less than the distance between the rims 3 and i,- thereby permitting the sections 6 and 7 to be easily and readily are placed in position between the rims 3 and 4c, the screws 141 are removed, thereby permitting the coil springs 9 to expand and hold'the rims3 and 4: in proper spaced relation and serve as cushioning means between said rims 3 and 4:. Each of the screws 14 comprises a cylindrical shank havinga hexagonal nut 15 formed integral with the .medial portion thereof and a threaded portion 16 which is-adapted to be inserted in placed in position. After sections 6 and 7 i the recessed bosses 12 while the opposite end of the screw 14 is adapted to rest within the alining bosses 13. The screw 1a is also provided with an annular groove 17 which is adapted to be in alinement with the openings 18 formed in the bosses 13, whereby a pin 19 'may be inserted through said openings, to lock the screw 14: in position. v It will be manifest that after removing the pins 15), the, screws 14 may be readily removed. The screws 14: are preferably removed from one section at a time. To provide means for preventing dirt and other foreign matter from accumulating between the sections of the cushioning device, I inclose the same by side plates 20 secured upon each side of the vehicle wheel, the inner marginal edges of said plates being permai'iently secured to the inner rim 3 by securing members 21 or the like, while the outer edges of said plates project beyond the outer rim section (3. The side plates 20 are connected intermediate of their inner and outer edges by the connecting members 22 extended between the outer and inner rim sections 6 and 7 and between the springs 9 and screws 14, as will be clearly understood by referring to Fig. 1 of the drawing.

, While from the foregoing I have described and shown the specific embodiment of the present invention it is of course to be understood that other minor detailsas to changes, formation, alteration and modification may be resorted to that come within the scope of the present invention without departing -members' between said inner and outer rims,

outwardly directed flared smooth sockets carried on the inner rim, inwardly directed threaded sockets carried on the sections of the outer rim, said smooth and threaded sockets being positioned opposite one another and adapted to receive a removable assembling tool, and a securing pin removably engaged transversely through one side of each smooth socket to lock the tool in position. 1

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

JOHN W. NIPPERT.
